I have a project in which a datasource programmatically created in a standard JVM, must be used for the connection pool and I cannot create and keep and entitymangerFactory so I'd like to set the entitymanagerFactory's connection pool. But I do not know how to stop the EMF from creating its own pool and make it use the datasource provided pool.

Easy peasy!

Fork my High-Performance Java Persistence GitHub repository and check out this test case.

You can configure the DataSource as you want and just pass it via the hibernate.connection.datasource configuration property.
